The Spiral 2 project at GANIL aims at producing exotic ion beams for Nuclear Physics. The accelerator of the primary beam is a superconducting Linac designed to provide 5 mA deuteron beams at 40 MeV. It will also allow accelerating stable ions of different Q/A values ranging from protons to Q/A=1/6 heavy ions. The accelerator should be commissioned by the end of 2011, first beam in 2012. The first tests aiming to produce exotic beams are planned one year later. The superconducting LINAC consists of 12 low beta (0.07) quarter wave (88 MHz) superconducting (SC) cavities and 24 beta (0.14) SC cavities integrated in their cryomodule. The status of the low beta cryomodules, supplied by the Irfu institute of CEA Saclay, is reported in this paper. The RF full power tests were performed on the qualifying cryomodule at the end of 2008 and the beginning of 2009, and the tests of the first series cavity in vertical cryostat are in course
